Abstract

This invention is directed to an extractor wherein tubular knitted fabric is ballooned, prior to the extraction of, usually water from the fabric, in an arrangement comprising a nip formed by two rolls. A tubular knit fabric additive applying mechanism is formed by providing a reservoir consisting of these two rolls and sealing or dam members disposed at each of the opposite ends of the above mentioned rolls. A single drive is provided one roll and functions to drive the second roll and a third roll disposed to form a nip with the second roll to extract excess additive from the fabric as it passes through the last mentioned nip. A method of applying an additive to a tubular knitted fabric moving the fabric through a nip to extract liquid therefrom and then immediately subjecting the fabric to an application of additive and immediately following this application by subjecting the fabric to the removal of the additive in a second nip.

Dependent claims

In a ballooned fabric extraction apparatus comprising:

(a) an extraction chamber for treating tubular knitted fabrics;
(b) said extraction chamber including a fluid and liquid fabric application arrangement in the internal portion of said extraction chamber;
(c) means for the extraction chamber to move the tubular knitted fabric to the internal portion thereof;
(d) first- means for the extraction chamber to guide said tubular knitted fabric in a predetermined direction in said extraction chamber;
(e) said fluid and liquid fabric application arrangement acting on said tubular knitted fabric to cause same to balloon;
(f) first and second roll means on said extraction chamber to form a first nip for receiving said tubular knitted fabric in a desired direction and in ballooned form from said extraction chamber;
(g) said first nip operative to smooth said tubular knitted fabric;
(h) one of said first and second rolls being driven so that said driven roll functions to move said tubular knitted fabric through said first nip wherein excess liquid in said fabric is removed;
(i) a third roll disposed relative one of said first and second rolls to form a second nip;
(j) an additive supply reservoir formed by said first and second rolls to serve as a bath for said tubular knitted fabric when it is desired to apply an additive to same;
(k) a dam means at each of the ends of said rolls to cooperate with the first nip to limit leakage of said additive from said reservoir;
(l) said third roll also being driven by the first or second roll whereby said tubular knitted fabric moves through the reservoir to the second nip so that excess liquid is removed therefrom;
(m) condensate disposal means arranged relative said second nip to receive excess additive therefrom;
and
(n) an additive supply means connected to said reservoir.
